Effect of the Venous Pressure to the Blood Pressure Signals Measured by the Electronic Palpation Method.

摘要

This paper describes the venous pressure effect to blood pressure signals measured by the electronic palpation method. It was shown, that in 52 percent of blood pressure measurements made with inflating cuff the linear increase in venous blood pressure was also increasing palpated signal's amplitude linearly. It was found, that the strong increase in venous pressure was not the reason for increased blood pressure amplitudes. The method for determining venous pressure by the electronic method was considered. The electronic palpation method can be used for venous pressure measurement if it is made with inflating cuff and secondly with deflating cuff. In the beginning of the measurements blood pressure should be monitored in the absence of cuff pressure for determining the venous pressure at rest.
